2 kubotans with dagger blades

Here are 2 kubotans I received this week. A friend from USA send them to me, as a gift.

There are two colors, the silver one is from stainless steel, while the black one is from regular steel and is gun blued; blades on both of them are made from stainless steel, are both edged and both razor sharp.

The handle has 15 millimeters in diameter and while it's closed, it's 105 millimeters long. It has rough grooves  on the outside, for much much better grip. If you unscrew the last part of the handle, you get out 60 millimeters long dagger style blade, that can be screwed back to handle, and you get a knife.

On bottom, there's a drilled through hole, that has attached a keychain ring, so it can grab your thumb.

Quite simple, effective and dangerous weapon!
